4. The display device according to claim 1 , further comprising: a manipulation detection sensor that detects, on the display screen, a manipulation of moving a data image toward the part of the display screen on which the portable information terminal is arranged, wherein the display device transmits data to be transferred to the portable information terminal to the storage device to cause the storage device to store the data in the data area.

5. The display device according to claim 4 , wherein the display device causes the display screen to display an instruction image indicating a download instruction to read the data stored in the data area to notify the portable information terminal of the download instruction, and wherein the portable information terminal reads the data stored in the data area of the storage device in response to the download instruction.

6. The display device according to claim 5 , wherein the display device causes the display screen to display the instruction image blinking, and wherein a temporal change of the blinking indicates the download instruction.

7. The display device according to claim 1 , further comprising a manipulation detection sensor that detects, on the display screen, a manipulation of moving a data image toward the part of the display screen on which the portable information terminal is arranged, wherein the display device requests from the storage device a uniform resource locator (URL) used to locate data that is stored in the storage device, wherein the display device receives the URI, from the storage device, and causes the display screen to display a link image indicating the URL to notify the portable information terminal of the URL, and wherein the portable information terminal reads the data stored in the storage device through the URL.

8. The display device according to claim 7 , wherein the display device causes the display screen to display the link image blinking, and wherein a temporal change of the blinking indicates the URL.

9. A data transfer method performed by a display device, the data transfer method comprising: transmitting a data area generation instruction to secure a data area in a storage device when it is detected that a portable information terminal is arranged on a display screen included in the display device; receiving information indicating a location of the data area from the storage device; causing the display screen to display a storage location image including the information indicating the location of the data area on a part of the display screen on which the portable information terminal is arranged; and notifying the portable information terminal of the location of the data area through the storage location image.

10. The data transfer method according to claim 9 , further comprising: reading data that the portable information terminal stores in the data area of the storage device.

11. The data transfer method according to claim 10 , further comprising: causing the display screen to stop displaying the storage location image when it is detected that the portable information terminal is removed from the display screen; and transmitting a deletion instruction to delete the data stored in the data area and the data area in the storage device to cause the storage device to delete the data and the data area.

12. The data transfer method according to claim 9 , further comprising: detecting, on the display screen, a manipulation of moving a data image toward the part of the display screen on which the portable information terminal is arranged; and transmitting data to be transferred to the portable information terminal to the storage device to cause the storage device to store the data in the data area.

13. The data transfer method according to claim 12 , further comprising: causing the display screen to display an instruction image indicating a download instruction to read the data stored in the data area to notify the portable information terminal of the download instruction, wherein the portable information terminal reads the data stored in the data area of the storage device in response to the download instruction.

14. The data transfer method according to claim 13 , wherein the instruction image is blinking, and wherein the temporal change of the blinking indicates the download instruction.

15. The data transfer method according to claim 9 , further comprising: detecting, on the display screen, a manipulation of moving a data image toward the part of the display screen on which the portable information terminal is arranged; requesting from the storage device a uniform resource locator (URL) used to locate data that is stored in the storage device; receiving the URL from the storage device; and causing the display screen to display a link image indicating the URL to notify the portable information terminal of the URL, wherein the portable information terminal reads the data stored in the storage device through the URL.

16. The data transfer method according to claim 15 , wherein the link image is blinking, and wherein the temporal change of the blinking indicates the URI.

17. A display device, comprising: a display panel including a display screen for displaying an image; a processor; and memory coupled with the processor, the memory storing instructions, when executed by the processor, causing the display device to at least: transmit a data area generation instruction to secure a data area in a storage device when it is detected that a portable information terminal is arranged on the display screen; receive information indicating a location of the data area from the storage device; cause the display screen to display a storage location image including the information indicating the location of the data area on a part of the display screen on which the portable information terminal is arranged; and notify the portable information terminal of the location of the data area through the storage location image.

18. The display device according to claim 17 , wherein the instructions further cause the display device to read data that the portable information terminal stores in the data area of the storage device.

19. The display device according to claim 18 , wherein the instructions further cause the display device to: cause the display screen to stop displaying the storage location image when it is detected that the portable information terminal is removed from the display screen; and transmit a deletion instruction to delete the data stored in the data area and the data area in the storage device to cause the storage device to delete the data and the data area.

20. The display device according to claim 17 , wherein the instructions further cause the display device to: detect, on the display screen, a manipulation of moving a data image toward the part of the display screen on which the portable information terminal is arranged; and transmit data to be transferred to the portable information terminal to the storage device to cause the storage device to store the data in the data area.
